Looking for a coarse thread Milano oil pressure switch for the dummy light. Centerline is out of stock and I can't seem to find one elsewhere. Dm me if you have one you'd like to part with!

Thanks.

just check out blue streak standard ps189 at your local jobber i believe that's what your looking for
I hate to say it but I've never seen the word jobber used before. could you describe it for me? Sorry for my Americanness:LOL:
edit: Found out the meaning and the part.

I get that it is the right part but I'm not sure if its the fine thread or the coarse one. They are different sizes. I have already tried a fine threaded sender and it doesn't fit. I believe the measurement I found on the boards is that one is a 10mm x 1.00 and the other is a 10mm x 1.25. I need the latter.

A jobber is an aftermarket parts retailer - includes auto parts stores such as Pep Boys, Napa, Advance... anything but the new car dealer's parts counter.

Are you sure about the thread? The only M10 x 1.25 switch I can find is intended for the RX8 and has three terminals. Centerline just mentions coarse and fine threads. Could it be something else? You will have to pull the switch and measure.

M10 1.25 seems so peculiar that I would suggest to use a steel adapter if space allows, and use a more common M10 x 1.0 switch. Not sure the one on my link would be the right one, the description is a bit shallow. A competent machinist could make one as well. Avoid brass, it fatigues and will crack.

I haven't pulled the switch to measure but I got the info from a thread on the boards here by Alfisto Steve . I'll link it below.

Using the part numbers quoted by Steve, I found this European page that lists a bunch of equivalents. I typed the numbers on Rockauto and they carry Facet 70007 for about $5 which they list for VW and Volvo applications. Now the page I got this numbers from includes the thread description as M10 x 1.0 tapered. Maybe Steve got it wrong? Maybe that catalog page is wrong ? They do list a Delphi switch with NPT thread and a Bosch switch complete with crush washer as equivalents.

That part number does seem to fit many Fiat/Alfa/Lancia applications, none of which made it over here. If all else fails, you should contact an European Alfa parts specialist who deals with post 105 cars, Such as EB Spares or Highwood Alfa in UK.

Just a bit more research in Rockauto's humongous catalog gave this interesting WVE entry for a VW/Audi switch that includes the Milano for 1987 only. For a few dollars, I would give this and/or the Facet 70.007 a try.

Wow thanks for all the help guys! I look up that part number from jett's comment and I found this on ebay. Does this look correct? Guess I could always ask seller to double check the measurements if possible.

Hello

With the information Mike (Jett) added above, the part number I started with is not relevant for the coarse thread gizmo. He's a second generation Alfa parts specialist, you can trust him. I first met his father at the parts counter of our main Alfa dealership 43 years ago.
